Diurnal asymmetry of climatic response to increased CO₂ and aerosols: forcings and feedbacks

To examine the causes of the observed diurnally asymmetrical climate change over land, the roles of different physical mechanisms are evaluated using a radiative-convective model of the diurnal cycle. This model explicitly calculates a complete set of physical processes, including the water vapor distribution, clouds, transports in the turbulent boundary layer, and convection. Calculations were carried out for midlatitude summer and winter and for tropical spring conditions taking into account the most important climate forcings: CO₂ increase, tropospheric aerosol pollution, and the combined case with simultaneous CO₂ and aerosol effects. -from Authors
